Write a library of static methods RawPicture with read() and write() methods for saving and reading pictures from a file. The write() method takes a Picture and the name of a file as arguments and writes the picture to the specified file, using the following format: if the picture is w-byh, write w, then h, then w × h triples of integers representing the pixel color values, in row-major order. The read() method takes the name of a picture file as an argument and returns a Picture, which it creates by reading a picture from the specified file, in the format just described. Note: Be aware that this will use up much more disk space than necessary—the standard formats compress this information so that it will not take up so much space.
